STAPLE-BINDING DELIVERY MECHANISM FOR PRINTING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 615,253, dated December6, 1898.

Application filed June 14, 1895. Serial No. 552,808. (No model.)

To all whom it may concern:

Be it known that I, LUTHER C. CROWELL, a citizen of the United States,residing at New York, (Brooklyn,) county of Kings, and State of NewYork, have invented certain new and useful Improvements inStaple-Binding Delivery Mechanism for. Printing- Machines, fullydescribed and represented in the following specification and theaccompanying drawings, forming a part of the same.

The object of this invention is to provide a rapidly-operating machinewhereby many sheets of paper or similar material, whether associatedtogether so as to have raw or cut edges or folded so as to have at leastone folded edge or plicated in any other way so as to constitute a pack,may be bound together so as to constitute a single product by means ofstaples set in, on, or near the binding edge or line of fold,whichsheets may be fed within the range of action of the traveling tools ofthe stapling mechanism byhand or otherwise.

The type of stapling mechanism upon which the present invention is animprovement is generally shown in Patent No. 510,528 and morespecifically in Patent No. 510,843, in which the staple presenting andsetting tools are transported to and from the setting-point in arotative carrier, which carrier contains a rotative staple-formingmechanism which supplies the staple to the presenting-tool.

The invention may be broadly stated to consist in novel constructions ofrotative mechanisms whereby not only is high operative speed attained,but great certainty of performance is assured in the operations'of.

forming and setting the staple.

The specific features of invention are so fully hereinafter explainedand finally set out in the claims as to need no preliminary description.

A practical embodiment of this invention is shown in the accompanyingdrawings, which illustrate an apparatus designed to form a part of thesheet-delivery mechanism of a perfecting printing-machine.

In the drawings section-lines mark the plane in which an illustration ismade, the reference-number for the line indicates the figure whichembodies the view, and the arrow-head connected with each section-linepoints the direction in which the picture is seen. Feathered arrows showthe direction of movement of the part or parts with which it isassociated and like reference characters completely formed and deliveredwithin the staple-holder in advance of the staple inserting tool ordriver. Fig. 2 exhibits a similar View of the same parts, but indifferent positions, the staple in this instance having been insertedinto the material and its legs having been clenched down thereon. Fig. 3exhibits a longitudinal sectional elevation of the cylinder or supportthat carries the Wiresupplying, staple forming, holding or presenting,and inserting tools, the view being taken on the section-line 3 of Fig.1 and some obstructive parts removed to more clearly expose others. Fig.i'exhibits a front end elevation of the same cylinder or support as seenon the section-line 4 of Fig. 3. Fig. 5 is a sectional plan view of theparts shown in Fig. 4 as seen looking in the direction of the arrow 5.Fig. 6 is a side elevation of the same parts as seen looking in thedirection of the arrow 6. Fig. 7 is an end elevation, partially insection, of the cylinder or support carrying the wire-supplying, stapleforming, holding, and inserting tools, the parts being in the positionsshown in Fig. 2, but the section is taken on the line 7 of Fig. 8 tomore particularly illustrate the wire-feed. Fig. 8 exhibits-an insideelevation of the stapling mechanisms, showing more particularly thewire-feeding devices as seen looking in the direction of the arrow 8 inFig. 7. Fig. 9 exhibits'a rear elevation, with some parts broken away,of the rotative staple-forming anvil and'the stapleleg-bending arms, oras seen looking in the direction of the arrow 9 in Figs. 1 and 11, whenthe staple is in course of formation. Fig. 10 exhibits a side elevationof thesame parts as seen upon the section-line 10 of Fig. 9. Fig. 11 isa sectional plan view taken on the section-line 11 of Fig. 10. Fig. 12is a perspective view of the staple holder or presenting tool removedfrom the machine and partly broken away to exhibit its interiorconstruction. Fig. 13 is alongitudinal sectional elevation of the stapleholder or presenting tool taken on the section-line 13 of Fig. 10. Figs.ll and 15 are views similar to those of Figs. 10 and 13, respectively,but exhibiting a modified construction of the staple-presentin g tool.

In order to readily understand this invention, it may first be statedthat the staple holder or presenting tool 10, which delivers the stapleto the material M in which it is to be set, and the clenching-die 11,which bends down or clenches the staple-legs upon said material, areeach carried in a support that is rotative, the said supports, asillustrated, being cylinders A B; but the office of these cylinders inso far as each tool they carry is concerned being merely to support suchtool in such a manner that it may move or travel to and from thestaple-setting point for cooperative action with reference to saidmaterial all unnecessary parts of such cylinders might be removed or anyother suitable support be adopted; butit is sometimes desirable to havesuch supports in the form of cylinders, as will hereinafter appear, andhence they are so shown.

In Fig. 1 the traveling staple-holding tool 10 and the travelingclenching-die 11 are shown as moving rotatively onward toward thesetting-point, traveling in the same direction in which the material Mis moving, and thus approaching the same from opposite sides thereof,which material is illustrated as being fed onward between and past thesetools by means of feeding-rollers *0 -11. In Fig. 2 the supportstherefor have so far moved as to have carried the staple-holder 10 andthe clenching-die 11 into such complete cooperative relation at thestapling-point and in coaction with the staple inserting tool or driver12 as to have accomplished the operations of presenting the staple tothe material, inserting it therein, and clenching its legs thereon, sothat the staple-crown bears upon one side of the material and its legsupon the other side of the material, the plies of which material arethus embraced or bound together. The plies of material thus fed onwardand united together by staples may be two or any other number, thefeeding-roller 40 having its journals carried by bearers 4-2, that arespring-seated in holders 43, thus being arranged to accommodate anythickness of the material,wl1ich may vary considerably in thickness.

The feeding rollers t0 t1 may receive the material from any source ofsupply, and it may be in web form or in sheets. The webs or sheets willpreferaly be led through these rollers 40 il or directly between thecylinders or supports A B from the machine producing them-as, forinstance, a printing machine or machines-and either before or afterbeing stapled together may, if requisite, be divided transversely orboth longitudinally and transversely into sheets of any desired size. Iffed to the machine in sheet form, then the sheets may be delivereddirectly to the stapling mechanisms or between the cylinders or supportsA I which carry such mechanisms, or the sheets may first pass betweenthe said rollers 40 41.

There will be one or more stapling mechanisms, according to the numberof staples it is desired that the binding-line shall contain. Herein(see Fig. 3) two is the illustrative number selected, and they arealined parallel with the shafts of the cylinders or supports A B. Theplicated material M will thus be fastened together by a line of staplesset in the material transversely or at right angles to its plane ofonward travel past the stapling mechanisms.

Vith this preliminary description as indicative of the general operationthe construction and operation of the stapling mechanisms will now bedescribed in detail, and as the two sets are duplicates it will beunderstood that a description of one applies equally to both.

As herein embodied, the supports illustratively chosen for the staplingmechanisms are cylinders A B, which are respectively mounted upon shafts5O 60, that turn in journals supported by suitable framing, concertedrotation of said cylinders being accomplished by intermeshing wheels ontheir shafts, to which motion is imparted in the usual manner; but whererollers 40 ll are used as the feeding device for the material M theywill also be geared so as to run in unison with said cylinders A B. Thisgearing is not shown, as it is common; but it may be here remarked thatif this stapling mechanism is made part of the delivery apparatus of amachine producing the sheets or webs of material then said gearing willbe properly connected with said machine so as to cause the two to run inunison.

Except in Figs. 14 and 15, the staple holder or presenting tool 10 issheath-like in its construction (see Fig. 12)thatis, it is provided witha longitudinal guideway of dimensions suiting it to receive the formedstaple and admit of the same being moved longitudinally through and tobe discharged from it; but instead of being a sheath with continuouswalls its central portion might be cut away and thus constitute it oftwo arms seta suitable distance apart and each having a guiding-channel,which channels 16 17 would face each other, as in Fig. 15. This holder10 is preferably arranged to slide longitudinally in a stationary wayformed in an inwardly-projecting bracket 51, (see Fig. 7,) that isfastened by screws to the shell of the cylinder A, and that part of saidholder facing the rotating forming-anvil is cut away centrally to form amidway recess 2, that provides for the entrance of the end of said anvilas it sweeps into the staple-holder, carrying with it the formed staple,(see Figs. 1,12, 13, 14, and 15,) which recess for the anvil and stapleis provided in the sheath form of Fig. 12 by cutting away the centralbody of the lower member of said holder, and in the modification, Figs.14 and 15, is provided by the widthwise space between the two armshaving the channels 16 17. Openings aeare cut through the holder, so asto intercept its guiding-channels 16 17, into which openings a 6 narrowportions of the plates 7 9, containing the channels 14 15, project, asshown in Figs. 9, 10, and 15, to form a substantial continuity betweenthe channels 14 15 and the channels 16 17. To advance the staple in thisholder for presentation to the material and to cause the staple to beinserted into the material and its legs to be clenched thereon, thesettingtool or driver 12 is arranged to reciprocate in said holder. Thisdriver is a plate-like tool or device that is guided by its edgessliding in the grooves or channels 16 17 of the holder 10, and itsmovements are imparted to it by means of a lever 31, whose free end isslotted to admit of the traversing movement of the lever over the pinthat connects the two, said lever being fast to a rock-shaft 32, that isjournaled in bracket-arms 52, which project from and are fast upon theshaft 50, and said shaft 32 is suitably rocked to move the driver bymeans of a rock-arm 33, the stud 45 of which runs in the slot of a cam34, that is made fast by means of a sleeve embracing the shaft andhaving a flange by which it is bolted to the framework. (See Fig. 3.)

The holder 10, when constructed to slide, is maintained in its foremostor projected position by means of a spring 13, fastened so that it bearsagainst alug 3, that is carried by the holder, and which lug 3 alsooperates to limit the range of the outward movement of the holder, andthus determine the extent to which the said holder protrudes beyond thecylinder A or other support or beyond the plane of travel of thematerial to be stapled.

While other means for supplying the holder 10 with staples which willcause them to be passed through a midway passage in the body of theholder and be deposited in the guidingchannels thereof in advance of thedriver 12 with their legs pointing outward may be adopted, that hereinshown is preferred as one of advantageous construction, and especiallyso because it is not only rotative in its operation and thereforecapable of high speed in delivering a staple to the holder orpresenting-tool, but for the reason that it additionally forms thestaple it delivers by a rotative action. This rotative staple-formingmechanism consists of stationary staple-bending arms 4 6 and arotatively-moving forminganvil 5, which sweeps between said arms.

The bending-arms 4 6, as shown herein, are.

parts of circular plates 7 9, that are held in place by flanges, throughwhich they are bolted to the shell thereof, so as to project into thecylinder or support A, and -saidbending-arms are formed by piercing saidplates with wire-channels S,which are enlarged, as in Fig. 9,to permitthe necessary movement of the wire ends as they are being bent intostaplelegs. The rotative forming-anvil 5 is an arm adapted to -sweeppast said bending-arms 4 6 and to move between the inner walls of theplates 7 9, being mounted adj ustably upon a shaft 20, that is journaledin brackets 53 54, (see Fig. 3,) fast to the inside of the cylinder, andwhich shaft passes through said plates 7 9. This shaft is suitablyrotated by means of a toothed wheel 61, fast upon one end of it, whichthrough an intermediate 62 is driven from a toothed wheel 63, that iscarried by a sleeve 64, surrounding the shaft and fastened by its flangeto the fixed framework. (See Figs. 3 to 6.) These plates 7 9 have cutinto their inner faces staple-legguiding ways or channels 14 15, thatare intercepted by the wire-passage 8, which guideways or channels areeccentric with the shaft 20 or axis of motion of the forming-anvil 5 andgradually extend outwardly from the wire-receiving point or passage 8 tothe staple-discharging point or where they direct the staple midway intothe staple holder or presenting tool 10, the staple passing through thewidthwise recess in the said holder, which recess connects said channels17 16. The plates 7 9, the guiding ways or channels 14 15 therein, andthe axis of the anvil 5 are so related to the plane in which said holderis positioned that this may be accomplished and the end of the anvil notonly sweep into the holder 10 to deposit the staple therein, but swingfree from the staple it has formed and delivered into the holder, thusmoving onward to repeat its functions, as will more clearly appear inthe setting forthof the operation of the mechanisms.

The propelling operation of the anvil 5 not only operates to form thestaple-legs substantially at right angles to the crown of the staple,but, cooperating with the channels 14 15,

maintains this relation of them while operating in connection with saidchannels to carry the staple to the delivery-point and elevate the sameuntil its discharge into the channels or guideways 16 17 of the holder10 is accomplished.

In order to insure the proper position of the staple in the holder 10,so that each staple will be securely lodged therein and accuratelyguided therefrom in the setting operation, ad-

. vantageis taken of the resilient action of the wire from which thestaples are made, so that the tendency of the staple-legs to move apartmay be utilized in securing the proper position of the staple in theholder with respect to its ejecting-guideway. Thus, as is shown in Figs.12, 13, and 15, the guiding-channels 16 17 in the holder 10 are enlargedlaterally at the receiving-point for the newly-formed staple, whereby asthe staple is carried into said channels 16 17 by the propelling actionof the anvil 5 and its legs pass out of the channels Ll 15 said legs mayexpand into the enlarged portions of the channels 16 17, as shown insaid figures, said enlarged portions of these channels thus operating asshelves to support the formed staple by its expanded legs in the planeof movement of the setting-tool or driver 12 and preventing the staplefrom moving downward. These channels 16 17 in advance of thereceiving-point for the formed staple, which is about midway of theholder, are gradually contracted to dimensions which are equal to thewidthwise extent of the staple when its legs stand at approximatelyright angles to its crown. By this construction said guideways orchannels 16 17 will operate, as the driver 12 advances, as guideways,preventing the legs deviating from a true rightline onward course in thesetting plane, or that of the movement of said driver, and at the sametime act to gradually compress the staple-legs toward each other, so asto attain the right-angular position referred to, which will beaccomplished as soon as the staple has passed out of the enlarged partsof said channels and reached or passed into the said channels in theforward part of the holder, said legs thus passing around the recess 2and openings a e, the result being that the staple is in absolutecontrol of rigid holding parts from its formation to its setting. Thecylinder or support A also carries within it the wire supplying andfeeding devices, the shell of said carrier being provided with aremovable section 66 to admit of the introduction of the spools and alsoof adjustmentof the parts and repairs thereto. Long lengths of suitablewire are wound upon spools S, that turn on a shaft 21, whose bearingsare in brackets fixed to the cylinder A. The wire therefrom is led pasta curved guiding-plate 35, thence between frictional feeding-rollers 2228, thence through a guiding eye plate or block 24, (see Fig. 11,) andis finally entered into the wire-passage 8. The upper one, 22, of thefrictional wire-feeding rollers 22 23 is on a stud suitably supportedand is driven by means of a bevel-wheel 36 on said stud, which mesheswith a similar bevel-wheel 37 on the shaft 20.

The wire-cutting device consists of a suitably-shaped arm 1, (see Fig.11,) that is fast on the shaft 20, and it is provided with a cuttingedge that sweeps between the plate 7 and the guiding-block 24 and inshearing relation to the outer surface of said plate 7. It is shown (seeFigs. 1 and 2) as moving concertedly with the anvil 5 and operating tosever the wire slightly in advance of the impingement of the anvil 5thereon; but this condition maybe changed to suit the speed ofoperation, the size of the wire, or any other conditions which mayaffect its operation.

The means for clenching the staple-legs as here shown consist of a blockor die 11, that is fastened to the cylinder or support B, so as to moverotatively therewith. In its face there is formed a groove of the lengthof the staple, the ends of which are tapered or rounded inwardly, as maybe its sides, so as to progressively bend the staple-legs toward eachother and center or aline them as they are pressed into it, and saidgroove is shallow enough to cause said legs as they are bent to approachand finally lie flat upon that side of the material opposite to the sidefrom which they were entered into or passed through it.

The machine being set in motion the operations will be as follows: Thewire is fed forward into the wire-passage 8, and when a suitable staplelength extends therein the rotative cutter 1 and the rotative anvil 5act in their rotative circuit, the cutter to sever the wire length andthe anvil to intercept its body or crown portion, as in Fig. 9, andcarry the same onward before it. As the anvil begins to press the wirelength onward it first acts to draw the projecting ends of the wirelength out of the wire-passages 8, then forces them over thebending-arms 4 (J, and then draws them into the channels or guideways 1415 in the plates 7 9, thus converting said ends into legs and completinga staple. The crown of this staple rests against the forward face of theanvil, while its legs, which lie against the sides of the anvil, areconfined in the channels 11 15, (see Fig. 1.0,) and hence as therotative circuit of the anvil is continued the staple-legs,controlled bysaid eccentric guideways or channels, cause the staple to beprogressively moved outward as it travels onward, the crown of thestaple movingradially and passing over the face of the anvil. Vhen theentrance recess or way 2 into the staple holder or presenting tool isreached, the occentric guideways or channels in the plates 7 9, actingas an elevator, will raise and guide the staple into said holder orpresenting-tool, and as the staple is then advanced into the channels 1617 of the holder the crown of the staple is moved off from the anvil 5,the staple being thus deposited in the holder or presenting-tool withits crown lying in front of the driver 12. The staple-legs, no longerconfined by the channels 14 15, but having been drawn out of them, willexpand by their resiliency and lightly press against the outer walls ofthe enlarged channels 16 17 of the holder or presenting-tool, said legsextending forward or in the direction of the setting movement. As theanvil thus freed from the staple it has formed and transported into theholder 10 moves onward rotatively to repeat its operation that part ofthe cylinder or support A from which the staple holder or presentingtool protrudes will be approaching the staple-setting point, as in Fig.2, and the cam 84 will cause the inserting-tool or driver 12 to moveforward, carrying the staple before it, so that it may finally standsupported in the mouth or end of the holder or presenting-tool, duringwhich forward or longitudinal movement of the staple in the holder orpresenting-tool 10 its legs, pressed IIC through the contracted portionsof the channels 16 17, have been gradually bentinto rightangularrelation to the staple-crown ready to be set.- When the cylinder orsupportA causes the presenting-tool to press into contact with thematerial M that is to be stapled and against the companion cylinder orsupport B or its clenching-die, the staple-legswill pierce the materialand enter the clenching-die, and thus the holder or presenting-tool willbe progressively pressed rearward again st the resistance of its spring13, while the driver 12 will remain stationary,thereby causing thestaplelegs to be bent or clenched upon the material M. When the staplehas been completely set by having its crown pressed against one surfaceof the material M, whileits legs are clenched down upon the oppositesurface, as in Fig. 2, the holder or presenting-tool will, continuing tomove onward in its rotary circuit, be again protruded, the driver 12will be retracted, the wire will be fed into the passages 8, theformingeanvil will rotate, and the operations described will berepeated.

The clenching device ll'has been described as traveling rotatively withits support, as the cylinder B. It is, however, practical and sometimesadvantageous to have the clenching-die remain stationary, in which caseit may be supported in the requisite position to coact with the othermechanisms in performing its function of clenching the staple-legsduring the operation of setting the staple. In such operation of itthere should be a clearance in a downward direction for the clenchedstaple-legs, in order that when the staple-legs. are pressed onto thematerial they may be carried onward with the same without obstructingsuch movement or injuring the material.

The staple-bound material may be conveyed to any suitable cuttingmechanism for severing it into sheets; but the same may be arranged forcoaction with the other mechanisms, if that arrangement is preferred.When arranged to operate in direct connection with the other mechanisms,the cutting devices may be independent of the cylinders or supports A Band may have combined with them means for folding the staple-boundsheets in,

on, or near their stapled line of union, or the folding mechanism,whether it be of the rotative or reciprocating type, may be arranged tooperate before, after, or during the cutting operation.

It has been stated that it is sometimes desirable to have the supportsfor the stapling mechanisms in the form of cylinders. if the saidsupports are also to act as carriers for any part of the material thatis to be stapled, as would be the case if the feedingrollers 40 41 wereomitted and the material fed directly to or between the said supports,they would in cylinder form impinge upon and feed the material forwardor otherwise cause the material resting thereon to be carried onward.Then these supports are cylinders,

Thus

they may not only carry cutting mechanisms for severing the materialinto sheet lengths, but support folding devices for doubling or foldingthe sheetsupon their stapled line of union. Herein, as illustrative ofthis, the cylinder A is provided with a cutting-blade 44, thatcooperates with a suitable cutting bed or slot provided in the cylinderB, and the latter is provided with a rotative foldingblade 45 46, thatis adapted to cooperate with a pair of folding-rollers in doubling thesheets transversely. Then the material is thus to be severed into sheetsand folded, the cylinder B will have sheet-carrying grippers orequivalent front end engaging devices to carry the sheets onward.

It is to be observed that herein the forminganvil bears upon the entirecrown-forming portion of the wire length not only during the formingoperation, but while carrying the formed staple onward for delivery.This is of great importance in mechanism having this mode of operation,because it prevents the staple-crown from kinking or bending, from whichmight result such a projection downward as would prevent the clearanceof the forming-tool 5 in its rotary sweep through the holder 10 afterhaving delivered the formed staple therein.

The staple-forming anvil 5 is shown to be adjustable on itscarrying-shaft by means of a holding screw 48. Of course any other meanssecuring this adjustment may be adopted, the object being to fix therelative movement of the anvil with respect to the setting movement ofthe driver 12.

WVith respect to the holder or presentingtool 10, which has beendescribed as being sheath-like, as shown in Fig. 12, and in a modifiedform as consisting of two opposed arms, as illustrated in Figs. 14 and15, it is to be observed that Fig. 14, being taken on the section-line14 of Fig. 15, shows a facial View of the arm containing the channel17,- and it is to be noted that in the sheath form the tool has areciprocating motion and in the modified form shown in Figs. 14 and 15it is a stationary device. Of course there might be a bridge-bar leadingfrom one arm to the other at their forward ends, said bridge-bar beingprovided with a lug to operate as does the lug 3, and-thus convert theseseparate stationary arms into a moving structure, suitable guides beingprovided for them to move in.

Where the holder or presenting-tool reciprocates, it is obvious that theopenings a 6, provided for the protrusion therein of portions of theplates 7 9, so thatthe channels 14 15 therein may intercept andcommunicate with the channels 16 17 in the holder, must be elongated, asshown in the drawings, to admit of the reciprocation withoutinterference with said plates.

As herein illustrated, the enlarged parts of the channels 16 17 areconnected rearwardly as well as forwardly with the enlarged portions ofsaid channels by angular portions.

Of course this is not essential in the rearward direction, but ispreferable, since it accommodates the shape taken by the staple, andthus said staple in its entire transit through the holder has its legscontinuously supported.

The combination with stationary plates provided with eccentricguiding-channels for the legs of a staple being carried onward, an anvilrotating between said plates and operating as a carrier, and areciprocating stapledriver, of a staple holder or presenting toolprovided with opposed longitudinal guidingchannels for the staple-legs,with which said eccentric guiding-channels connect between its ends,said channels in the holder being enlarged to admit the spreading of thestaplelegs therein, and being brought to parallelism in the direction ofthe setting movement of the driver so as to contract the staple-legsinto setting position, substantially as described.

13. A stapling mechanism consisting of a carrier provided with means forclenching the staple-legs and of a rotating carrier supporting withinitsshell the Wire holding, feeding and cutting devices, and the stapleforming, presenting and setting devices, substantially as described.

14. A staple holder or presenting tool provided with opposedlongitudinal channels for the guidance of the staple-legs andsettingtool or driver, a portion of each of said chan-' nels beingenlarged and joined at both ends to the main part of the channel byangular portions and said holder having a lateral passage leading tosaid channels, wherebya staple formed with its legs approximately atright angles to its crown may be delivered through said passage intosaid holder, and its legs be spread apart in said enlarged channels soas to support the staple, and its outspread legs be contracted tosetting form in moving through saidholder, substantially as described.

15. The combination with a rotary anvil, guiding-channels through whichthe staple is moved by the anvil in its rotation and a second set ofguiding-channels connecting with the first and placed tangentially withreference to the path of the anvil in its rotation whereby as the anvilrotates the staple carried by it is successively moved through the firstguiding-channels into the second guiding-channels and then out of thepath of the anvil, substantially as set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
